Book Description
Informatica—the updated edition of Alex Wright's previously published Glut—continues the journey through the history of the information age to show how information systems emerge. Today's "information explosion" may seem like a modern phenomenon, but we are not the first generation—or even the first species—to wrestle with the problem of information overload. Long before the advent of computers, human beings were collecting, storing, and organizing information: from Ice Age taxonomies to Sumerian archives, Greek libraries to Christian monasteries. Wright weaves a narrative that connects such seemingly far-flung topics as insect colonies, Stone Age jewelry, medieval monasteries, Renaissance encyclopedias, early computer networks, and the World Wide Web. He suggests that the future of the information age may lie deep in our cultural past. We stand at a precipice struggling to cope with a tsunami of data. Wright provides some much-needed historical perspective. We can understand the predicament of information overload not just as the result of technological change but as the latest chapter in an ancient story that we are only beginning to understand.

Book Description
Este libro explora los 5 principios que definen a una "ciudad de código abierto" a través del estudio del caso de la ciudad de Raleigh, en Carolina del Norte. Se analiza cómo las características de la metodología empleada en el desarrollo de software de código abierto, es decir, la colaboración, la transparencia y la participación, entre otras, están dando forma a los movimientos por un gobierno abierto (open government) y por una información accesible y reutilizable por parte de los ciudadanos y organizaciones (open data). La cultura en materia de código abierto, la política municipal y el desarrollo que se ha producido en los últimos años en esta población son un ejemplo que sirve como guía para aquellas ciudades que busquen el sello de "ciudad de código abierto".
